create a python program for this.

Create a Refund class that inherits from Netflix. This class tracks the most recent premium, family, normal, student, and ad subscriptions sold. The most recent transaction can be retracted and the subs sold in it can be refunded by a refund rate. Initial refund rate is $50\%.$

For ease, copy your code for Netflix into the code cell for this problem, and then change the encapsulation on all of its fields from private $($double underscore$)$ to protected $($single underscore$).$ For Refund, however, encapsulate the fields as private.

The Refund class must implement$/$override the following methods:

$(1)\_($self$)$: initializes additional fields$-$the most recent transaction and the refund rate

$(2)$ sellSubscriptions$($self$,$ premium, family, normal, student, ads$)$:

if there isn't enough room, this method ends and prints "Total cost is $0\mathrm{.}00$ PHP$"$

otherwise, this method tracks the latest transaction, and then calls sellSubscriptions$()$ on its superclass

$(3)$ refund$($self$)$:

$$ the available room is adjusted to reflect the refunded subscriptions

$$ the cost of the most recent transaction is deducted from total sales at the refund rate

$$ the money that was refunded this time is printed out

$$ the tracking of what was the most recent transaction is reset to nothing

prints out $"$No Refund Available." if the most recent transaction has no current value

$(4)$ updateRefundRate$($self$,$ newCost$)$: updates the refund rate based on the value of the parameter

On a separate code cell, do the following instructions in the same sequence:

$(1)$ Create a Refund object

$(2)$ A customer attempts to buy $30$ premium, $114$ family, $308$ normal, $52$ student, and $17$ ads

$(3)$ A customer attempts to buy $200$ premium, $109$ family, $260$ normal, $231$ student, and $57$ ads

$(4)$ A customer attempts to buy $200$ premium, $20$ family, $30$ normal, $10$ student, and $5$ ads

$(5)$ The most recent customer refunds their tickets

$(6)$ Someone is trying to do a refund again

$(7)$ It is end of day

$(8)$ Print the report

$(9)$ Someone is trying to do a refund... SCAM!!

$(10)$ Due to the panic that these scammers cause, refund rate is decreased to $35\%$

$(11)$ A customer attempts to buy $500$ premium, $309$ family, $170$ normal, $131$ student, and $57$ ads

$(12)$ A customer attempts to buy $400$ premium, $100$ family, $50$ normal, $100$ student, and $50$ ads

$(13)$ The most recent customer refunds their tickets

$(14)$ It is end of day

$(15)$ Print the report
